Answer:
The coefficient of variation is 72.66%
Step-by-step explanation:
Data : 3 , 5 , 12 , 3 , 2
We are given that The mean of the sample is 5.
Formula of standard deviation =
Substitute the values :
Coefficient of variation=
Hence The coefficient of variation is 72.66%
Answer:
53.702
Step-by-step explanation:
You split the two numbers into two.
24, 0.41, 2, and 0,2
Then multiply each one by each other
2 x 24
2 x 0.41
0.2 x 24
0.2 x 24
24 x 2
24 x 0.2
0.41 x 2
then add all of them together and you get your answer
(3x+4)(2x+1)
If the question asks you to find roots/solutions:
3x + 4 = 0
3x = -4
x = -1.33333333
2x + 1 = 0
2x = -1
x = -0.5
